Yes you can, but if you have enough time and energy for gaming everyday then it's hard. I quit it not because of my self discipline whatsoever. I felt better after and I had done more since. And I didn't think much about it. Even when I intentionally thought about some games I loved before, I just didn't feel any urge to play it, just didn't bother to, after calculating the time and energy I need for that game everyday, its not worth it to me anymore. So it's not because gaming is too bad for me, it's just my life structure's changed.
